As an adult, the gametophyte … WebIn plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Are seeds haploid or diploid?

Spore Reproduction in Plants and Other Organisms - ThoughtCo

WebThe zygote immediately undergoes meiosis to form four haploid cells called spores. Although haploid like the “parents,” these spores contain a new genetic combination from two parents. The spores can remain dormant for various time periods. WebAfter reaching maturity, the diploid sporophyte produces spores by meiosis, which in turn divides by mitosis to produce the haploid gametophyte. Therefore life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte. fallgaiz

"WebThe haploid spore or diploid zygote of land plants initially undergoes more or less continuous, sequential mitotic cell divisions. Later, as gametophytes or sporophytes mature, active cell divisions become restricted to certain regions of the plant. This region of actively dividing cells is known as a meristem.
